MP3 experiment on Wednesday

Depending on how many people show up, it could be pretty awesome: A Montreal edition of Improv Everywhere’s MP3 Experiment is set for Wednesday at 5:17pm.

Instructions are here and there’s a Facebook page. No RSVP required, just show up wearing red, yellow, blue or green and carrying an uninflated red or green balloon to a retail store on Ste. Catherine St. between St. Alexandre and St. Laurent.

Improv Everywhere’s MP3 experiments are explained here, but in short they involve a large group of people downloading an MP3 audio file, then playing it on headphones at exactly the same time. To the outside world, it just looks like a bunch of people wearing headphones, but who suddenly all start doing the same random things together.
